Transformer based controller for 3~ motors
5-step controller inclusive integral thermistor releasing unit
Type: R-DK...KT(G)
Examples of applications for controlling 3~ fans in 5-steps
Manual 5-step speed change-over of one or more 3~ fans e. g. in:
heat exchangers (as warm-air heaters), hoods, ventilation of rooms.
An integral thermistor releasing unit type U-EK230E with ATEX-approval can be used for the temperature monitoring
of motors in explosion protected range. Six thermistors (DIN 44081 or DIN 44082) can be connected in series.
According to the type of motor at least two or three single sensors are installed. Fans used in explosion protected
range must have three single sensors. That means at most two motors of this type can be connected.
The device includes potential-free and 230 V power on contacts for the connection of damper control motors or gas
valves (hoods application) (see on back).
Equipment Enclosed version IP21 / 54
Transformer based controllers for voltage controllable 3~ fans
•
5-step switch for manual speed control
•
Remote control (ON/OFF) via potential-free contact
(terminals „RT”-„RT”).
• Motor protection using thermistor connection (terminals „T1"-„T2").
If one of the thermistor is released, the unit switches off and not
on again. Restart after cooling the drive unit by switch-off and after that
switch on the mains voltage or by step-switch („reset").
•
A power on lamp is integrated.
• Automatic switch on after power failure.
• Additional power on contact
- Potential-free changer
- 230 V switched and constant voltage
